Fifty years on from Princess Grace and Prince Rainier's historic trip to the country, in 1961, Prince Albert's engagements include inaugurating an exhibition at Farmleigh House in honour of his late mother.

The sovereign prince and his fiancée were greeted by the Irish President Mary McAleese and her husband in Dublin, a day after the palace announced that Charlene had converted to Catholicism, Monaco's official religion.

A statement from the principality read "Miss Charlene Wittstock who professes the Christian faith, has been admitted by free and personal choice into full communion with the Catholic Church."
